<VV> Re: Oil use

[Bill Elliott]

In general I understand that "high mileage" oils differ from normal oils 
only in that they have a seal conditioner designed to help swell seals 
and reduce leaks. I've also heard that the additive package is better 
suited to handle blow-by contamination (but have never seen that verified).

If the SuperTech oil meets current certification requirements, I'd think 
it would be satisfactory... better than the stuff our cars were 
originally designed to run on.

I don't see any harm in using either of them, but my Corvairs all get 
5W-50 Castrol Synthetic.
